SCP Foundation provides examples of the following tropes:
- Names to Run Away from Really Fast: A group calling itself "The Chaos Insurgency" cannot possibly be up to any good. Neither can the Church of the Broken God.
- Nanomachines: SCP-204-1 is a particularly fight-prone cloud of those that eats meat. SCP-784-ARC is a man who now "lives" as a nanomachine colony. And SCP-1322 has plenty of nanomachines being delivered as a weapon.
- Narrator: SCP-1376 is a video camera that gives its recordings a narrator a la certain British nature documentaries.
- Subject: A static recording of a tennis ball placed on a table.
Narration: As noon approaches, it grows increasingly confused, as the creatures around it show no sign of using it for its intended purpose. Struggling to attract their attention, it becomes ever more distressed as it finds itself completely immobile.
- It may also be psychic (or at least very observant):Subject: An incidental recording of Dr. ██████ made by Dr. ████████ during unrelated experimentation.
Narration: Despite the male's calm facade, his lust for his female companion is extraordinary. The degree to which his obsession reaches has become nearly unhealthy, dominating his thoughts at every turn. Wild fantasies course through his mind when he watches her when she doesn't notice.
Researcher Note: Dr. ██████ was treated for a broken nose after being attacked by Dr. ████████ and both researchers have been placed on administrative leave for a period of no less than two (2) weeks pending disciplinary action and transfer to another site.
- Necessarily Evil: The SCP Foundation recognizes that it does very bad things, for the greater good of humanity.
- The "Unfounded" mini-canon is built on the premise that this is not true, taking place in a universe where there is no Foundation, and yet things are still pretty much the same, with other Groups of Interest taking up the slack.
- Necessary Weasel: The Foundation uses ordinary (that is, not paranormal) drugs which can erase memories. Nothing like that actually exists, but they're necessary to maintain The Masquerade, which is itself necessary for Plausible Deniability.
- One short story posits that instead of drugs, Class A Amnestics are good old-fashioned psychological torture and brainwashing.
- Next Sunday A.D.: A few Series 3 SCPs start in dates after their initial publication, such as 2015 (SCP-2716), 2016 (SCP-2242), 2017 (SCP-2703), 2018 (SCP-2570) and 2019 (SCP-2217). It probably works better than Series 2 dating articles with predictions such as SCP-1032's Euclid revision set for January 2015 or SCP-1023 having the California Collapse in 2016. SCP-2998 plays with it - it starts in the same 2013 it was written, then the aliens invade in 2017, and ultimately a Reset Button is pressed and time goes back to 2013 again.
- Nice Job Breaking It, Hero!: Has its own page.
- Nightmare Fuel: In-universe:
- SCP-425: A television set which broadcast weird vision by itself on the 8th, 16th, and 24th day of each month, even when unplugged. It's harmless, but if you born on days of the month that are multiples of 8 (e.g. 8, 16, and 24), then the vison will include moving through a black hole, and experience "a crushing sense of oblivion". Then you will have recurring nightmares for weeks, and even extensive psychotherapy only reduced the nightmare to once a month.
- 30% of SCP-1881-B players report lasting psychological effects afterwards, in the form of nightmares related to its contents (and occasional visual/auditory hallucinations).
- Nightmare Fuel Station Attendant: SCP-2980, a Big Red Devil that switched from terrorizing cultists to writing children's books. He likes reading his stories to anyone around his "nightlight" at 8:30 PM and the only effects these stories have is they sometimes give the listener a refreshing sleep and create new creatures to bedevil the Foundation like THE DEER (AKA "Damnbi") and Grog the cave monster .
- Whoever or whatever Phobos Labs ("Bringing your nightmares to YOU since 1944") is made SCP-2850, wasps that cause you to grow extra teeth which hatch more wasps which then hide in yours and any other human dwelling to find more people to infest. They also mention making TrypanoClowns©.
- Junior Researcher James, who's implied to be Dr. Bright's son. Two of his SCP's , SCP-789-J and SCP-078-J, which are funny if not childish. Then we have SCP-682-J, which are his drawings of SCP-682 and his versions of its description. One of the picture is SCP-682 eating a researcher.
- Nightmare Retardant: Invoked with the staff assigned to SCP-2006, a sentient sphere that can transform itself in order to cause fear in others. To prevent it from becoming something truly dangerous, staff members must watch low-quality horror movies and pretend they're terrified to trick it into only turning into harmless things.
- Nightmarish Factory: SCP-001:05. A factory built by a wizard that used Blood Magic and Soul Power to manufacture Organic Technology from the slaves bred in the factory's basement. The founder accidentally made a Pact with the entity running it, and every so often a researcher disappears... This might be why the Foundation is so quick to send D-Class personnel to their deaths. If it can gorge on Red Shirts, it'll leave the more valuable people alone.
- 90% of Your Brain: SCP-1475 took a drug that allowed him to use 100% of his brain, giving him complete and total control over his body. Unfortunately this also means that he now must manually do everything his body used to do automatically, like pumping blood through his veins or digesting food. This takes so much of his concentration that it has left him bedridden and unable to walk around because he can't move his muscles and keep up the formerly automated stuff at the same time. The author wrote this SCP specifically because they hated the "__% of your brain" trope.
- Nintendo Hard: Invoked by SCP-1633, which learns from players' actions and evolves to counter them.
- Nobody Here but Us Statues: SCP-173, in a manner similar to The Weeping Angels.
- No Dialogue Episode: SCP-2521 is this out of necessity, as it is a weird Humanoid Abomination that destroys anything written about it and kidnaps anyone who talks about it. However, drawing pictures that describe it is just fine.
- No-Holds-Barred Beatdown: SCP-517's reaction to SCP-087 in Episode 7 of Old Kansas Sector.
- "No. Just... No" Reaction: 076's reaction to being requested to approach one candidate for SCP-001.
- Any time experiments are cancelled on SCPs that violate common sense or would possibly replicate something nasty.
- No Name Given: The O5. Most of the time, even their identification numbers are blanked out. Often, researchers have their blanked out. D-Class, being expendable, don't have names, just numerical designations.
- Averted with O5-12, the father of SCP-321, whose first name is Adam in a nod to the long tradition of meaningful names and nods towards The Bible in the Foundationnote .
- Non-Indicative Name: This tends to come up a lot when discussing the Foundation's means of categorizing SCPs, mainly because when a Foundation operative says an object is "safe", they mean "nothing will happen if it's left alone in a locked room". A hydrogen bomb is "safe" by those standards.
- Non-Malicious Monster: A number of SC Ps are essentially just predatory organisms with anomalous traits.
- Noodle Implements: Some of the SCP objects become this, when SCP numbers are listed in incident reports or other articles; occasionally the SCP with that designation will appear completely irrelevant to the context in which it was referenced.
- That's often due to the original SCP being removed, and a new one filed under that number.
- Speculation on what Procedure 110-Montauk is at times gets comparable to The Aristocrats - a FAQ had a bunch of [DATA REDACTED]s interspersed with mentions of an elephant, a bed of live cobras, Barbara Streisand's Greatest Hits, something that is over seventeen feet long, a staple remover, a feather boa that absolutely must be black (and not dark blue), and "plutonium splitting the atom."
- On the other extreme, there are the containment methods of SCP-1746 and the process to activate SCP-1731's anomalous effects.
- Noodle Incident: Every single time you see "[DATA EXPUNGED]" or "[REDACTED]"; it seems like the whole idea is to have at least one such incident per SCP. The unspecified reason why SCP-447 must never come into contact with dead bodies is especially noodly and is occasionally referred to elsewhere (as seen below, it scares O5-2 shitless).
- Noodle Incident played for Squick and horror rather than laughs.
SCP-231 is essentially a
- Related to this is the notorious "Procedure 110-Montauk". Whatever you think it is, it's much, MUCH worse... and even then, it's much worse than that.
- The uncensored reports of SCP-835 demonstrate exactly what could be behind every Noodle Incident, and why you really don't want to know.
- On the other hand, it can also be seen as how a [DATA EXPUNGED] can be important for an article, as some people found the uncensored 835 reports to be quite disappointing.
- Most of the items on the list of things Dr. Bright is not allowed to do at the Foundation imply quite a few such incidents coming from just one guy.
- The first thumbnail in SCP-1231 is redacted, which is odd, considering that whatever you think the thumbnail contains is then created as a new thumbnail, and that the thousands of other thumbnails all derived from the first perception of the original.
- The entirety of SCP-579.
- Whatever lead to the photograph of SCP Agents wearing assless chaps out in public to contain SCP-1570. (NSFW, obviously.)
- Noodle Incident played for Squick and horror rather than laughs.
- No OSHA Compliance: In the SCP articles themselves, the containment procedures are designed to minimize danger, risk, and loss of life, even of the utterly expendable D-Class. In the testing logs, the prison-recruited D-class personnel are regularly treated to definitely unethical and probably lethal experimentation, often in cases where little useful information is likely to result, and are often subjected to the machinations of some of the more diabolical SCPs purely for the amusement of the ranking research staff.
- No Sell: Former SCP-151-D exhibited this along with other Marty Stu traits, shrugging off effects of other SCPs just because. His termination log consists much of the same, until he's finally destroyed... rather messily.
- No Sense of Direction: SCP-920, also known as Mr. Lost. Try to take him somewhere, or just walk with him for a while, and you will get lost. (However, apparently because all the super-deadly gets old if everything is super-deadly, the description has a notice that lost means "lost" as in "misplaced" and not some horrible fate. However, you can be lost to pretty much anywhere in the world. And it's likely you'll still die of thirst or cold if you get lost with him in a desert or a snowy area.)
- When they tried to contain him, a whole facility got lost. It remained where it was but nobody could ever find it, leading to its closure due to running out of supplies.
- Nose Shove: SCP-108.
- Not-So-Harmless Villain: Many of the SCPs. In particular is SCP-387, a set of sentient Legos. Ordinarily they're benign, and even kind of cute. But put a knockoff set of Legos nearby, and they will do something Redactable.
- Not Using the "Z" Word - The entry for SCP-008.
- Nothing Is Scarier: The guidelines for writing new SCP reports encourage vagueness so that the reader fills in the horror for themselves, which is more effective than detailing something that may just fall flat.
In the event of an unsuccessful Action 10-Israfil-B, no further action will be necessary. [DATA EXPUNGED]
- SCPs SCP-055 is a good example of this.
- Judging by the details of one uncensored article, everything behind those [DATA EXPUNGED] is worse than you think.
- However, if an expungement is poorly executed, it won't be very scary at all.
- SCP-579. What is it? We don't know. Whatever it is, the SCP Administration felt it was so dangerous that even the description of it is gone. They even killed all the people working on it, save 7 agents that act as advisers in case it ever gets loose. It's so bad that it's currently stored in an alternate universe — after having destroyed at least 4 other containment sites, with a very specific containment procedure, and if it ever fails, even for a minute, policy is to destroy the alternate universe to contain it. And if that fails?
- In-universe: SCP-1057. It's a space of air with no mass or anything that can be measured, in the shape of a shark. The only reason the SCP foundation knows it exists is because its form becomes visible in water. It has killed several people at the beach where it was discovered, and behaves like a normal shark otherwise. The chilling part? It is heavily implied that it does not exist at all, and that the illusion that it exists was created when someone at a beach said that there was a shark.
- Nuclear Option: Most (if not all) Sites have on-site nuclear warheads, to be detonated in the event of a breach by a Keter-class SCP or Site failure.
- But they are actually afraid to try it on SCP-682 because it might not only survive, it could become even stronger.
- The Nudifier: The intended use of SCP-1755 by its creators, until the Foundation contained it and discovered that the worms are bringing the cotton plant close to extinction and might cause a collapse in the textile industry.
- Number of the Beast: While SCP-666 is not overtly Satanic, SCP-616 is decidedly more hellish, and has clergy on staff when necessary. The actual religious requirements are invented, though.
- Nutritional Nightmare: SCP-807, the Heart Attack on a Plate. Any food placed on it will be turned into this trope, and consuming it will invariably cause a heart attack within 5 minutes.
- Obsessive Love Letter: SCP-1269, apparently a mailbox that sends stalkerish letters to female owners.
- SCP-962, which sends such love letters to humanity.
- Odd Couple: SCP-1710 1 and 2, an Eldritch Abomination and a pleasant British housewife, respectively, who were turned into trees by a Trickster God.SCP-1710-1: We were not always thus. We were the Serrated Void. We were That Which Rends. We were blades, edges, angles. We moved, we ravaged, we sharped.
SCP-1710-2: What was that? Sorry, I was distracted by those bees. Silly little buggers, they are, buzzing about. Oh, they tickle so!
- Oh, Crap!: From the Incident Report "Duke 'Till Dawn:" Containment of Keter level threat SCP-682 compromised.
SCP-507-A Oh. Bugger.Closing Statement: Subsequent testing revealed that SCP-507's abilities have no biological basing, and that severed pieces will still “shift” along with the main body.
- In interview 507G, Said by an alternate version of SCP-507 after he realizes what's going to happen to him.
- Omniscient Council of Vagueness: Aside from the Foundation, there's SCP-1659 AKA Directorate K, whose affected "members" number in the hundreds of thousands. Its mission is incomprehensible beyond apparently wanting to fix the SCP-verse in its own way and influencing foodies.
- Omniscient Morality License: A lot of these researchers are worse than Class-D personnel (Who are "recruited" from prison.) Some get demoted to Class D.
- Dr. Clef's version of SCP-001 has up to 108 wings and SCP-065's spherical area of effect originally had a 108 meter radius.
- SCP-2814, a mask that basically turns the wearer into a fire-bender, was stolen by a cult called the Children of the Sun which caused the deaths of 108 people (that the Foundation knows of).
- SCP-2108 has a lot of the same themes as SCP-2814 and it's related SCPs being a small sun, the number 108, attraction to crows, transformation abilities but there's no connection according to word of god (who hadn't read the other SCPs); besides it isn't even from the same universe.
- SCP-2953 is a boulder (actually the corpse of a powerful kitsune) that can turn humans into foxes, and during World War 2 Japan's anomalous research unit used fragments to make 108 bullets for propaganda purposes in China:Using [SCP-2953] as a basis, we will "expose" uncooperative Chinese leaders as "demons" to their subjects.
- Orifice Invasion: SCP-2484, anomalous mayonnaise: "Masses from 235 g to 804 g will actively attempt to make their way inside vertebrate animals through any available means (including oral, nasal, aural, ocular, rectal, or genital orifices, open wounds, and sweat pores)"
- Our Angels Are Different - Averted as the Foundation goes to extensive lengths to document the fact that Dr. Clef's proposal for SCP-001 is indeed a bona fide Judeao-Christian Angel without any major subversions — and possibly the Jophiel himself, who guards the real, genuine Garden of Eden. It does however play more to the descriptions in Holy texts as opposed to cultural depictions, for instance appearing to have as many as 108 wings and being made of fire.
- Played Straight, though, with SCP-469. Disturbingly straight.
- Your mileage may vary with SCP-861.
- SCP-2610-A thinks his "visitor" is an angel ("Her flesh rippled and tore, and light shined through the cracks like the sun.") and she speaks to him, as he remembers it, like one: "'Soft and silent, Child of God,/for you have been chosen to lead His people/and create for Him a New Eden.'"
- Our Mermaids Are Different: SCP-327
- Our Werewolves Are Different: Happy Howlidays, a Christmas Episode, portrays five different types of werewolves, with Class-1 werewolves being fully voluntary and in control of their changes, while Class-5 werewolves are viscous killing machines that can spread their infection through contact alone, and are capable of regenerating from a single finger and coming back from death. The infection is neutralized by nutmeg.
- Overly Narrow Superlative: The SCP-2900 effect sometimes generates awards for these. Other times, it generates awards for actions that people want to forget.
- Painting the Medium: Has its own page.
- Panacea: SCP-500 are pills that cure any disease, but there's just about fifty of them and they're impossible to replicate perfectly (though knockoffs can work if you're lucky). Later, SCP-427: the Lovecraftian Locket was developed out of one of the pills and has eclipsed it in use, although with the possible side effect of mutating you into a squid.
- Parody Sue: Several. Most notably, SCP-10101-j (a parody of overpowered wish-fulfillment self-inserts), SCP-777-j (a parody of god mode black hole sues), and SCP-496-j (a parody of Purity Sues, whose name actually references the original Mary Sue). SCP-316, later terminated with extreme enthusiasm by the resident Wonka, reads much like one but was apparently intended as a serious SCP.
- Pay Evil unto Evil: Guest Researcher Dr W introduced an ordinary frightened kid to SCP-682, and then a kid of the same age with deadened emotional reactions. Both were messily killed by SCP-682. So, Dr. Clef promptly introduced Dr. W to SCP-682, with the same result."Fucking sadistic asshole. I've got no sympathy for that moron whatsoever. Introducing children to this fucking monster? What the hell…"
Assistant Director Clef
- Perpetual Motion Machine: So many SCPs (labeled ectoentropic) ignore the laws of thermodynamics, being able to produce infinite amounts of matter, energy, or their constant movements could be used as a power generation tool. Sadly, most are either too valuable or dangerous to use.
- Person of Mass Destruction: People who get SCP designations, and especially Keter classifications, are generally contained because they fall into this category.
- Pet the Dog - Most sentient SCPs are accommodated reasonably well, depending on their potential danger, ability to escape, and willingness to cause harm. The most (relatively) harmless are given furnished rooms and are generally given whatever they request, as long as it doesn't violate security. They are, of course, not allowed to leave the facility.
- SCP-103 was the only SCP that the Foundation actually released. It says something about the Foundation's Well Intentioned Extremism that a man who's only power is that he never gets hungry is the only SCP ever let go without being terminated (and even that is, according to the comments, a controversial decision). He got retconned to having worms in his stomach that fly out and eat people and having voluntarily reported back to Foundation care.
- Some of the SCPs are given the best care possible. Every effort is made not to upset the autistic girl, for example, and the harmless and friendly living eyeballs have free run of their site. And one of the first tests of the vending machine was "something Cassy will like," Cassy being a mentally normal young woman who exists in a 2-D world and was actually created by the Foundation itself.
- Several SCPs which fall into a self contained microcosm, pocket universe, etc, or other SCPs that were created by the Foundation on accident, respect or outright revere the Foundation. On the other hand, some fall into a Rage Against the Heavens.
- Some SCPs that are relatively harmless are just glad to have someone talking to / using them again, in many cases having been abandoned for years after their original owner died.
- SCP-2031 is a type of army ant that incapacitates large mammals before invading them, turning them into a colony, and mimicking their behavior with disturbing accuracy. It's also implied that this places the victim into an And I Must Scream situation. However, at one point, the Foundation sets up an experiment with a human family infested by the ants and a bunch of animals in the same situation. The ants inside the humans take care of the animals like a normal human does, herding groups and feeding them. One day, however, one of the colonies has to leave the animal corpse they're inhabiting since it can't be supported anymore. The human colonies then react accordingly, first prodding the corpse, and then later burying it solemnly when they realize that the animal's gone for good. At the end, it's stated that the Foundation will infest a Golden Retriever puppy for the human colonies. This may be the first time the Foundation has willingly accommodated a non-sentient SCP beyond what it needs.note
- Pieces of God: That particular faction's not called "Church Of The Broken God" for nothing.
- Plague Doctor: SCP-049. This being the Foundation, naturally he's a horrifying Deadly Doctor.
- Playing Card Motifs:
- SCP-952 is an anomalous young man implied to be a faun/satyr/Pan himself that goes by the name "Jack of Hearts." After finding a "Jack of Spades," the Foundation is pretty certain there's two other Jacks out there.
- SCP-2156 is a college student who became so obsessed with solitaire and its symbolism and numerology that she broke reality.
- Playing with Fire: SCP-2814 can give people this power, plus very delusional thoughts (or are they?). Its creator's true intention was to use the mask's victims to feed the sun ("Our Radiant Father"), but three other stars ("Father's brothers") are stealing the energy away — and the victims aren't quite dead, including the mask's creator (who realizes this probably wasn't the best way to help "father").
- Pocket Dimension: The Three Portlands, a pocket dimension that's connected to Portland, Oregon, Portland, Main and Portland, UK. 3Ports is essentially a refuge for anomalous humans and other beings, having their own microsociety, down to various paratech companies present in the dimension.
- Police Are Useless: How the Foundation sees the FBI's Unusual Incidents Unit. More recent works have begun to portray them as competent.
- Police Code for Everything: Mostly inverted by the things Dr. Bright is not allowed to do. However, there are codes for: Necrophilianote and the Bright Family Reunion.note
- Post-Modern Magik: The Foundation uses science to study many of the seemingly supernatural and/or magical anomalies.
- Power Incontinence: Apparently a problem with mammoths:
- SCP-2082: A wooly mammoth clone that caused uncontrollable Ice Age conditions; its species is implied to have caused the Ice Age itself.
- SCP-2184: A steppe (to distinguish it from SCP-2082) mammoth (just one) that destroys any technology created after the Stone Age; the more advanced the object is the larger and more destructive its effect. Its aversion to post-Stone Age technology is so great it walked through a forest fire unscathed because the fire was started with a match.
- The Power of Hate: The Brazen Heart, the cult behind SCP-2427, "express extreme animosity for the Foundation and humanity at large":The Christian tells you that hatred is wrong.
The Buddhist tells you that hatred is a distraction.
The atheist tells you that hatred is unhealthy.
[DATA EXPUNGED] tells you that hatred is fun.
Hatred, in reality, is your call to action. A stern command to fight when you witness filth in this world.
- Powered by a Forsaken Child:
- Power Perversion Potential: SCP-447-2 can be used as a personal lubricant, unless you're a necrophiliac.
- Pretty Butterflies: SCP-408 is a sapient flock of color-changing, illusion-creating butterflies.
- Primal Fear: Many of SCP-1881's stage iterations invoke these, such as a level appearing to be upside-down without gravity being reversed to match, a shmup stage with no enemies (leaving the player floating aimlessly through empty space for several minutes before the level ended), and being trapped in a maze with an increasingly large number of deadly creatures.
- Produce Pelting: SCP-504 is a breed of tomato that throws itself if someone cracks a bad joke. If the joke is bad enough, it will break the sound barrier.Item: Three mature SCP-504 tomatoes, one for each test subject.
Subject: After the introduction to the following news item, "Bomb blows hole in Lenin statue", the three following jokes were made.
Test Subject 1: Ooh, that's gonna leave a Marx.
Result: Tomato number one 'twitched', but did not displace from its original location.
Test Subject 2: BBC is just Stalin the good news.
Result: Tomato clocked at 152 mph. Chipped tooth and hairline jaw fracture.
Test Subject 3: That blows.
Result: Tomato clocked at [REDACTED]. Subject is hospitalized with a massive skull fracture.
- Interestingly enough, when told The Funniest Joke of All Time from Monty Python's Flying Circus, it exploded.
- When shown on a later episode of Saturday Night Live, high-speed photography showed that the tomato changed velocity several times (including a brief jump backward), as if unable to decide whether the sketch was genuinely lame or just "bad" in an ironic sense.
- Prophecy Armor: SCP-711 ("Paradoxical Insurance Policy"). SCP-711 is a device capable of receiving transmissions from the future. It has received one such transmission from a future Foundation agent, but the governing O5 Council has ordered that the transmission never be sent. Since the Foundation knows the message will be sent at some point in the future, as long as it hasn't been sent then the Foundation can't be completely destroyed, because that would leave no one to send the message.
- Public Domain Artifact - Spring Cleaning, a story involving a bunch of these.
- Public Domain Soundtrack: SCP-2424, a Mega Man styled video game boss that somehow ended up in the real world, has his own chiptune theme music that plays whenever he becomes actively hostile, and it sounds appropriately awesome (scroll to the bottom of the page to hear it). The song itself is RoccoW - "Break-A-Leg" from the free music archive.
- Pumpkin Person: SCP-2331 ("SCRAVECROW"). SCP-2331 is a scarecrow with a pumpkin head that has a flourescent blue glow inside it. He creates raves and acts as a DJ at them.
- Pun-Based Title - A few names assigned on the SCP lists: "The Pied Pipe", "Builder Bear", "Glory Hole" (a hole to another dimension)...
- Punny Name - The task forces are full of these - "Moloch 'n Load", "See No Evil", "Cater Duty", "The Suge Knights"...
- Purple Prose:
Excerpt: As the blistered moon sank higher into the clouds, from behind the last faltering light ray espied a wrathful visage. Shabathh Centhal'Pr, a spineless cur twisted into humanoid form. Its pernicious iniquity of unthinkable gyrations splayed errant madness, yet through the shroud one could see its face was quite rectangular.
- SCP-696's novel:
- Putting the Band Back Together: The point of the Resurrection canon is to do this, turning MTF Omega-7 "Pandora's Box" into MTF Alpha-9 "Last Hope".
- Pyrrhic Victory: The eventual termination of SCP-096, caused as a result of Incident 096-1-A
- Rage Against the Author: S. Andrew Swann's SCP-001 proposal.
- Rage Against the Heavens: For the Global Occult Coalition, one of the Foundation's rival organizations: if God exists, then it's their job to kill it.
- Rainbow Motif: One of the entries in the Log of Anomalous Items. All written text regarding a certain notebook will be one of six colors (red, orange, yellow, green, blue or violet).
- Ravens and Crows: SCP-2106 is a flock (or "unkindness") of ravens that can become a woman named Jessica.
- Reality Retcon: The "Big Bloop", a Real Life extremely loud underwater sound, was caused by SCP-169, an enormous undersea creature which is at least 1,000 km in length. The Foundation had a spy in the National Oceanic and Atmospheric Administration who tried to prevent the public from learning of the Bloop, but failed.
- Reality Warper: They are called "Type Greens". They are treated extremely seriously by both the Foundation and the GOC, because Reality Warping Is Not a Toy.
- Reality Ensues: Several SCPs take certain popular fictional tropes and show how they would work in a real-world setting.
- SCP-1575. It is a statue/fountain that, over the course of about a month, slowly transforms animals into humans when they drink from it. What sounds like a furry fetishist's dream quickly becomes a nightmare when you look at the concept from a real-world point of view. Simply put, animals and humans are biologically different for a reason. Only three tested animals managed to survive the transformation and only one of those three transformed fully with no unwanted results. The rest died from Transformation Trauma related defects, due to biological differences. Examples include a field mouse whose cardiovascular system shut down because it couldn't keep up with the rate her body was growing, a tiger whose organs failed after just four days because of the sedatives she was given, a parrot whose skeleton shattered in various places because, like the field mouse, it couldn't keep up with the rest of her (her wings did apparently manage to form a set of pseudo-hands, though) and some undisclosed but horrific incident caused because a dog used for testing was unknowingly affected with intestinal parasites.
- SCP-239 is a deconstruction of Haruhi Suzumiya-style Reality Warpers, showing just how dangerous a child would be when given these powers. Instead of being a super-powerful Little Miss Almighty, she is, whilst non-malicious, a confused, frightened little girl with potentially world-ending powers, which she can neither understand nor control. It gets to the point where keeping her in a coma is the safest way to contain her.
- In a different vein, we have SCP-1470. It's a spider who can communicate through telepathy. The Foundation no longer has to keep an eye on it, because it's dead. Spiders of that species only live for four months, and once those four months were up, it died of old age.
- Reality-Writing Book: SCP-140 is a very specific version; the book writes itself and alters reality as a consequence, given a suitable form of ink or ink substitute. SCP-687 is a text adventure video game with broader abilities.
- Reconstruction: The "Resurrection" Canon hub is a major attempt at reconstructing the so called "lolfoundation" ethos that fell out of favour several years previously.
- Red Shirts: The Class D's, of course. Lampshaded: Dr. Bright cannot change the standard issue D-Class uniform to black pants with a red polo shirt."84.1. I see your reasoning, but we just don't want to be associated with Star Trek."
- Parodied in SCP-2063.
- Red String of Fate: SCP-2203, a carnival "love machine" that can make perfect matches (it can even account for the subject being aromantic and asexual and match them up with perfect friends). As long as you follow it's hints on how to get close to your match and don't, for example, get matched with someone who's already happy with their partner or attack your match's current partner and get demoted to D-class everything will be just fine.
- Refugee from TV Land: SCP-2424 is a video game boss transported to the real world (given it's a Cyborg Walrus, probably a Maverick?). And apparently the protagonist appeared too, bearing a rather revealing document in his possession.
- Regional Redecoration: Has happened on more than a few occasions, but they've all been covered up as just being part of Earth's natural geography. For example, the Marianas Trench wasn't around before a massive containment breach. It also wasn't initially underwater.
- Released to Elsewhere: D-Class personnel are assured that they'll be freed at the end of the month if they cooperate ("released like homicidal bunny rabbits into the wild," as said in the D-Class Orientation). Even if they manage to survive the various monsters, artifacts, and testing procedures, they are still executed at the end of the month anyway.note
- Replacement Goldfish: SCP-1976 was made by a man to be this for his family after he died of a brain tumor. He thought its powers would make his family see it as their husband and father, instead it caused his wife to think it was her father while his children weren't old enough for its powers to work. It currently causes anyone within its activation criteria who looks at it to think its their father while their real father becomes a stranger.
- Research, Inc.: The Foundation benefits commercially from their research.
- Reset Button: SCP-2000. The article massively exaggerates the trope with relentless, non-stop technobabble and a very convoluted activation process, but is none the less played straight.
- Retcon: The Mass Edit, which was basically the wiki admins purging some of the more dubious entries and retconning out some of the more ludicrous (and humorous) aspects of the backstory. (See below.)
- Ret Gone: When Fishmonger (the writer) was banned, he demanded to have all of his characters and stories to be removed from the SCP Wiki. Some of his more famous characters were referenced in many articles. This left many gaps.
- And before that, all of the SCPs deleted during the Mass Edit.
- To make things even more confusing, since the numbers for Ret Gone SCPs were freed up, the wiki wound up with new SCPs under old numbers. The weirdest case being SCP-098, which is mentioned in Dr Clef's SCP-001 proposal because it was a Hell Gate, but now the number is used for crabs. ("Truly these are the crabs that bring about the apocalypse.")
- Revenge Before Reason: SCP-1322 is a hole to an alternate dimension, that after being accidentally hit with a Sterility Plague due to the Foundation, starts using said hole to send deadly weapons to our reality. Years after cutting contact, they still send it, often with the weaponry showing progress! Many the comments ask "why are they using their science for revenge instead of fixing the sterility"?
- Rock of Limitless Water: Inverted with SCP-402, which absorbs limitless water.
- SCP-045 is a straight example, producing water when exposed to nitrogen in an environment with less than 380 atmospheres of pressure.
- Roswell That Ends Well: It wasn't a spaceship; it was SCP-1051 prior to hatching, as well as a ruse to draw in victims.
- Room 101: The old SCP-100 entry is a port-a-potty that performs Mind Rape on anyone inside as soon as the door shuts. All the researchers could get from D-Class victims was that it grows enormous when the door is closed.
- Rule of Sean Connery: An In-Universe example in SCP-1781. A drive-in saw attendance rise with movies featuring Hugo Weaving, so the place started showing pictures that added Weaving to the cast (for starters, the page image is Weaving as Rhett Butler). invoked
- Rule of Seven: SCP-231-7, the last survivor of seven girls rescued from a Religion of Evil, and the seven chains that hold SCP-2317 (six are broken). Given both involve The End of the World as We Know It if broken, they're invoking the Seven Seals in the Book of Revelation.
- Rule 34: SCP-1004 is this in its purest form.
- Running Gag:
- Dr. King and apple seeds. Explanation
- SCP-447 must NEVER come into contact with a dead body.
- It also turns everything green with a minty smell/taste.
- SCP-055 is... Wait, what were we talking about?
- All Foundation personnel are reminded that the SCPs are to be treated as powerful and dangerous artifacts at all times. They are not for use in pranks, party games, or to help with your hangover. Explanation
- "Demoted to Keter Duty/D-Class" Explanation
- SCP Insert Number Here was used against SCP-682. Attempt failed.
